/**
 * The `NbSelectComponent` provides a capability to select one of the passed items.
 *
 * @stacked-example(Showcase, select/select-showcase.component)
 *
 * ### Installation
 *
 * Import `NbSelectModule` to your feature module.
 * ```ts
 * @NgModule({
 *   imports: [
 *     // ...
 *     NbSelectModule,
 *   ],
 * })
 * export class PageModule { }
 * ```
 * ### Usage
 *
 * If you want to use it as the multi-select control you have to mark it as `multiple`.
 * In this case, `nb-select` will work only with arrays - accept arrays and propagate arrays.
 *
 * @stacked-example(Multiple, select/select-multiple.component)
 *
 * Items without values will clean the selection. Both `null` and `undefined` values will also clean the selection.
 *
 * @stacked-example(Clean selection, select/select-clean.component)
 *
 * Select may be bounded using `selected` input:
 *
 * ```html
 * <nb-select [(selected)]="selected"></nb-selected>
 * ```
 *
 * Or you can bind control with form controls or ngModel:
 *
 * @stacked-example(Select form binding, select/select-form.component)
 *
 * Options in the select may be grouped using `nb-option-group` component.
 *
 * @stacked-example(Grouping, select/select-groups.component)
 *
 * Select may have a placeholder that will be shown when nothing selected:
 *
 * @stacked-example(Placeholder, select/select-placeholder.component)
 *
 * You can disable select, options and whole groups.
 *
 * @stacked-example(Disabled select, select/select-disabled.component)
 *
 * Also, the custom label may be provided in select.
 * This custom label will be used for instead placeholder when something selected.
 *
 * @stacked-example(Custom label, select/select-label.component)
 *
 * Default `nb-select` size is `medium` and status is `basic`.
 * Select is available in multiple colors using `status` property:
 *
 * @stacked-example(Select statuses, select/select-status.component)
 *
 * There are five select sizes:
 *
 * @stacked-example(Select sizes, select/select-sizes.component)
 *
 * And two additional style types - `filled`:
 *
 * @stacked-example(Filled select, select/select-filled.component)
 *
 * and `hero`:
 *
 * @stacked-example(Select colors, select/select-hero.component)
 *
 * Select is available in different shapes, that could be combined with the other properties:
 *
 * @stacked-example(Select shapes, select/select-shapes.component)
 *
 * @additional-example(Interactive, select/select-interactive.component)
